SP-GIEFTCATIONYformng part of Letters Patent No. 689,650, dated December 24, 1901.

Appiiman fnea March 5,1901. Seriana-19,684. or@ modem y To tu w/tom, it may concern:

Be it known that I, THOMAS JOSEPH MORI.- ARTY, a citizen of the United States, residing at Newport, in thecounty of Newport and State of Rhode Island, have invented certain new and useful Improvements in Depth and Rolling Recorders for Torpedoes, of which the following is a full and complete specificat ion, such as will enable those skilled in the art to io which it appertains to make and use the same.

This invention relates to torpedoes; and the object thereof is to provide a device for measuring at one test or experiment the rolling movement of a torpedo as it passes through I5 `the water and also the depth to which it passes in the water. It has been the custom heretofore to make each of these tests or experiments by separate instruments at different times, and this is an expensive operation,

2o as well as one which involves much time, by reason of the fact that the torpedo had to be discharged or red in'order to make one of ment being used for each. In my invention, however, I combine in a single device or instrument means for making both of said tests or experiments at the same time, and thus 3o save a great expense and also much time.

The invention is fully disclosed in the iOllowingspecicatiou, of which the accompanying drawings form a part, in which the separate parts ot' my improvement are designatedv by the same reference' characters in each of the views, vand in which- Figure 1 is a sectional plan View of the head of a torpedo provided with my improvement; Fig. 2, a partial longitudinal vertical section on the line2 2 of'Fig. l; Fig. 3, a transverse section on the line 3 3 of Fig. 2; Fig. 4, a transverse section on the line 4 4 of Fig. 2 looking in the direction of the arrow a; Fig. 5, atransverse section on the line 4 4 ot' Fig. 2 looking in the direction of the arrow o; Fig.

6, atransverse section on the line 6 G of Fig. 2;

Fig. 7, a transverse section on the line 7 701c Fg. 2; Fig. 8, a side View of a portion of the device for measuring the diving movement of 5o the torpedo; Fig. 9, an end View thereof and Vshowing the same in position in the instrument and showing the outer casing of said part removed; Fig. lO, an inside View of said casing; Fig. 11,'a plan view of a part of the instru ment used for measuringthe rollingmovement of the torpedo; Fig. 12, asection thereof on the line 12 12 of Fig. 1l Fig. 13, a partial section on the line 1313 of Fig. 8, and Figs. 14 and l5 are plan views of record-strips which I employ. 6o`

In the foreagfoing views ot' the drawings Figs. land 2 are on a reduced scale, but ot' the remaining views Figs. 3 to 12, inclusive, are of full size.

In the drawings forming part of this specication, reference being made to Figs. l and 2, I have shown at 5 the head of a torpedo, part of said. head being omitted in Fig. 2, and this head in actual use of the torpedo contains the explosive material and is known as 7o the war-head of the torpedo; but in the testing or measuring of the movement of the torpedo contemplated by this invention this head is lled with water or other material which Awill give to the torpedo the weight which it has in actualA use, or the war-head may be detached and a testing-head put in its place, and this head, as shown in the drawings, is provided with an opening 5a, to which issecured a screw-threaded collar 5b, pro- 8o vided with a tubular casing 5, and in the construction of my improvement I provide a tubular casing 6, provided at one end with a reduced screw-threaded extension 6, which is adapted tov be screwed into the collar 5", 85 and at the opposite end with a reduced screwthreaded lock ing-band 7 ,into which is screwed a collar 8,'having an enlarged outer end portion Sa, with which is connected, by means of a screw-th read or otherwise, a cylindrical cas- 9o ing 9, which is provided, preferably in the bottom thereof, with an angular opening 9a, into which is set a segmental plate 10, which is held in place by a sleeve 11, which is free to turn on the casing 9 and which is open at 95 one side, as shown at 11a, and the plate 10 is adapted to be inserted into position Within the cylindrical casing 9, of which it forms a detachable part, through the Opening 11a and to be removed through said opening whenroo ever desired. The cylindrical casing 9 is also provided with a transverse groove 9b, through which passes a pin, lug, or other device 11", secured to the sleeve 11, and said sleeve is free to tu rn on the Casin g, and by means thereof the opening 9a may be closed and the plate 1l) securely held in place.

The cylindrical casing 9 is provided at its front end with a thickened portion 9c, which is screw-threaded interiorly, and I also provide an annular head 13, provided with a screwthreaded neck 13, which is screwed into the thickened portion 9c of the casing 9 and with which is connected, preferably by means of a screw-thread a conical head 14. The annular head 13 is provided with an opening or openings 13", through which the water is free to pass, and the conical head 14 is provided with the usual propeller 15, having a screw-threaded shank 15, which passes through the end ot' the conical head 14 and is held in place by a nut 16, and said shank 15 is provided at its inner end with a pinion 17, which operates in connection with a gear-wheel 18, supported by an arm 19, secured to the annular head 13, and the wheel 18 is provided with a pinion 20, which operates in connection with a gear-wheel 2l, secured to a shaft 22, which passes inwardly through the neck 13 of' the annular head 13 and which is provided at its inner end with a pinion 23.

Within the tubular casing 6 is loosely placed a tube 24, which is free to turn in said tubular casing G and the outer end of which is provided with a tube or sleeve 25, which is eularged at its extreme outer end to form an annular casing 26, provided with an internal gear 27 and in connection with which the pinion 23 operates, and in practice the sleeve 26 and the tube 24 are turned by the pinion 23, and said sleeve or tube 25 is provided near its extreme outer end with an annulargear 28.

Within the neck 13" of the annular head 13 is secured a tube 29, which passes into the outer end of the tube 24 and with which is connected a tube 30 in which is placed a cupshaped piston 3l, and secured to the piston 3l is a spiral spring 32, which passes through the tube 29 and is connected .at 33 with the annular head 13, and the tube 30 is placed in communication with the open space in the annular head 13 by means of the tube 29 and a port or passage 34 in the neck 13L of the annular head 13. The tube 24 is provided at its inner end with a detachable tubular casing 35, the outer end of which is open, as shown in Fig. 10, and provided with a pinion 37, and the inner end of the tube 30 is closed by a detachable end piece 38, provided with an opening 39, through which passes the spring-arm 40 of a stylus 41, said arm being secured at 42 to the piston 31. The detachable end piece 38 of the tube 30 is provided with an arm 43, which is provided at the end thereof adjacent to the tube 30 with a support 44, which projects at a right angle therefrom, and at its opposite end with a support 45, which projects at a right angle therefrom, and mounted in the supports 44 and 45 are two shafts 46, one of which is provided with a gear-wheel 47 and is operated by the pinion 37. Each of the shafts 46 is provided with a tubular casing 48, on each of which is placed a sleeve 49, and said casing and said sleeve are adapted to turn one upon or one within the other, and this operation may be secured by means of milled heads 50, connected with said sleeve and said casing. One of the shafts 46 (that with which the gear-wheel 47 is connected) is rigidly secured to the tubular casing 48 through which it passes, and each of the tubular sleeves 49 is provided, as shown in Fig. 7, with a longitudinal slot 50, and each of the tubular casings 48 is cut away at one side or reduced longitudinally to form a space 51, and the sleeves 49 form rollers, on which is wound a record-strip 52, and in connecting the record-strip 52 with the rollers 49 the ends thereof are passed through the slots 50 into the open space 51 of the tubular casings 40, and said sleeve or casing is then turned so as to secure the ends of said strip in position. The details of this construction are best shown in Figs. 2, 3, and 7, and at one end of one of the sleeves or rollers 49 is placed a friction-spring 53, which prevents said sleeve or roller from turning too freely.

The spring-arm 40 of the stylus 41 passes through the bottom portion of the support 44, and the stylus 41 is directed downwardly, so as to bear on the record-strip 52, as clearly shown in Fig. 7, and said record-strip is pret'- erably composed of paper, paper and canvas, or other suitable material chemically prepared in such manner that the stylus 41 in moving thereover will leave a niark similar to the mark of a lead-pencil.

The sleeves or rollers 49, the record-strip mounted thereon, the stylus 41, and means for operating said rollers or sleeves and for operating the stylus,as hereinafter described, constitute the mechanism for measuring the diving movement of the torpedo, while the devices for measuring the rolling movement of the torpedo are placed in the chamber 54 within the casing 9, and which is closed by the plate 10. These devices are clearly shown in Figs. 2, 5, 6, 11, and 12 and consist of sleeves or rollers 55, through each of which is passed a tube 56, in each of which is placed a shaft 57, and the shafts 57 are supported by brackets 58, connected with the segmental plate 10, and one of the shafts 57is provided with a worm gear-wheel 59, which is operated by a worm-gear 60, supported by a shaft 61, and the shaft 61 is provided with a pinion 61, operated by the annular gear 28. The sleeves or rollers 55 are each provided witha longitudinal slot 62, and the tubes 56 are cut out correspondingly at one side to form longitudinal spaces 63, and these sleeves or rollers 55 are designed to receive a record-strip 64, which is wound thereon and the ends of which are secured thereto by being passed through the slots 62 into the spaces 63, after which said sleeves or rollers or said tubes are IOC . With the index-mark 69 on the torpedo.

turned so as to secure the ends o'f the strip in place. It will be understood, however, that one of the shafts 57 is secured to the tube 56, through which it passes, this construction being necessary in order that the rollers or sleeves may be operated by means of the gear-wheel 59. v

, Suspended from the top of the casing 9 are two supports 65, from which is suspended a swinging stylus-support 66, which is open at the center and through which the parts 25, 29, and 32 pass, and this stylus-support 66 is provided atits lower sidewith a stylus 67, which is adapted to bear on the record-strip 64 between the sleeves orrollers 65, and this mechanism, including the sleeves or rollers 55, the stylus 67, and the stylus-holder 66, together with the record-strip 64, constitute the means for measuring or recording the rolling movement of the torpedo. The plate 10 is also provided with a transverse support 68, over which the record-strip passes, the object of this construction being to provide a support for said strip in order that the stylus may properly operate thereon, and this record-strip is prepared in the saine manner asvthe corresponding strip on the sleeves or rollers 49. It will be understood that in the operation of this mechanism the stylus-support 66 must always hang in a vertical position, and in order that the recording device'may be properly connected with the torpedoI provide the head of the torpedo at the point where the connection of the recording device is made therewith and in a central vertical line with an indexmark 69, as shown in Fig. 1, and the casing 6 is provided with a plurality of corresponding marks v70.k The outer end of the collar 8, which is enlarged and designated by the 4reference character 8a, is also provided with an index-niark 71, andthe index-marks 69 and 71 are preferably designated on the Atorpedo and on the record device by zero, as shown in Fig. 1. In practice the casing c is screwed upuntil one of the index-marks registers The testing instrument or recording device is then turned until the index-mark 7l is in line with the index-mark 69, and the locking-band 7 is propeller 15 as the torpedo passes throughy the water. It also will be seen that the sleeve 25 is geared in connection with one of the rollers 55, on which the record-strip 64 is Wound, and in this operation the said strip is drawn from one of said rollers and rewound on the other. The tube or casing also turns with the tube 24, and the pinion 37, connected with said tube 'o'r casing,'operating in connection with the gear-wheel 47 on one of the shafts 46, revolves the sleeve or roller on said shaft,.and the record-strip 52 is drawn from one of said rollers and rewound on the other. As the torpedo passes through the Water the latter enters the recording device through the opening or openings lb in the annular head 13 and passes backwardl y through the neck of said head and through the tube 29 into the tube 30 and into the piston 3l and forces said piston backwardly, andv this pressure of course increases as the torpedo passes deeper into the water. The backward movement of the piston 3l operates in a corresponding manner the stylus 41, and said stylus moves back and forth across the recorderstrip 52, andas said recorder-strip 52 is drawn from one of the rollers or sleeves 49 onto the other an irregular mark is made longitudinally of said strip by said stylus. As the torpedo passes through the water it has to some extent a rolling motion, and the stylus 67 is intended to measure this motion on the record-strip 64, and an irregular line is made by said stylus longitudinally of said strip as the latter is drawn from one of the rollers or sleeves 55 and rewound on the other.

In Fig. 14 I have given a plan view of the record-strip 52, and in Fig. 15 a plan view of the record-strip 64, and these record-strips are of the same length, the strip 52 being preferably wider than the strip 64, and said strips are also provided with transverse lines 7 3, which are preferably numbered from one end of the said strips to the other, as shown in said figures, the numbers employed being 10 and multiples of ten and said numbers representing rods and multiples of rods.

After the experiment or test has been' made and the torpedo has been recovered the recording device is removed and taken apart and the record-strips 52 and 64 are placed side by side or edge to edge, and the variations or cnrvatures of the black lines 74, which are made by their respective styli as they pass over said strips, indicate the depth to which the torpedo has passed as it passes through the water and also the rolling motion thereof. In Figs. 14 and 15 the dotted lines 75 indicate what should be the movement of the stylus as it passes over these strips, and the object of making the test or tests is to cause the torpedo to move as .nearly as possible in a true line, and by adjusting the propelling and the steering mechanism of the torpedo this object may be approximately accomplished. It will be understood, of course, that the torpedo is weighted or provided with a keel, which holds it inthe proper position as it passes through the wa- -ter or keeps it right side up, and also with the usual mechanism for propelling and steering it, and by properly adjusting the steering and propelling devices or mechanism the control ofthe torpedo may be secured. If the torpedo rolls too much or the'diving IOO IIO

IZO

movement thereof cannot be controlled, it is practically useless to attempt to use the same in warfare or for any practical purpose, and it is absolutely necessary to control the rolling and diving movement of the torpedo, which can only be done by properly adjusting the propelling and steering mechanism and by knowing what the rolling and diving movement is in order that the adjustment of the propelling and steering mechanism may be properly made, and by placing the recordstrips 52 and 64 together in the manner herein described it may be determined at what point during the passage of the torpedo over its course the rolling and diving lnovements were irregular and too great, and the mechanism of the torpedo may be adjusted so as to overcome the difficulty.

It will be apparent that the piston 31 and stylus 4:1, connected therewith, are moved in one direction by the spring 32 and in the opposite direction bythe water entering said piston, as hereinbefore described. It will also be understood that my improvement, which I call a combined depth and rolling recorder for torpedoes, may be applied to any torpedo of the usual construction,whether the same be of the Whitehead or any other class, and it will be apparent that changes in and modiiications ot' the construction herein described may be made without departing from the spirit ot' my invention or sacrificing its advantages.

The torpedo-shaft 22 may be provided with any desired means for preventing leakage, and the propeller may be provided with ballbearings of the usual or any preferred construction, and the locking-band 7 may be turned by hand, if desired, orby any suitable means, and in practice the spiral spring 32 is made adjustable or so formed as to adapt the same to torpedoes of different speeds, it being evident that a spring for a torpedo ot' low speed would not be suitable for a torpedo of high speed.

The record-strip 52, in addition to being ruled transversely, as hereinbefore described and as shown in the drawings, is also ruled longitudinally, the longitudinal lines denoting feet and being numbered, as shown, and the point from which the stylus starts on this strip is designated by the reference-letter e, an'd by means of this arrangement it will be apparent that the movement of the stylus may be determined at a glance. The record-strip G4 may also be ruled longitudinally, if desired, and other changes in and modications ot' this construction may be made, as will be apparent.

Although I have shown and described my improvement as applicable to torpedoes, it will be apparent that the same may be applied to any submarine boat, vessel, or other object, and Wherever in this specification and in the following claims the Word torpedo is employed I desire it to be understood as including any kind or class of a submarine torpedo, vessel, or object designed or adapted to be propelled through water.
